A student made a model of an ecosystem inside a sealed plastic bottle. She placed soil, rocks, water, plants, and animals inside the bottle. How is the model like a natural ecosystem?

b. lithosphere, asthenosphere, mesosphere   is the answer most likely

ecological efficiency: % of usable energy transferred as

biomass from one trophic level to the next typical is 10% efficient (90% of

energy is lost),is diagramed as the pyramid of energy flow. then osprey eagle

are tertiary consumer and the shrimp are primary consumer, so to balance

mass of shrimp (1/0.1) / 0.1 = 100 kg
